MTL - My Inseparable House Guests - Chapter 2 Hurry up and help me

Rainer, an amateur arcanist and college student, sought to create a new spell far surpassing the magic of the few he inherited from his grandfather. Yet the interference of an unknown event during the casting of his spell led him to be thrown through space and time.

Thousands of years ago, the First Expungement came. The world changed, and humanity was nearly wiped out. Thankfully, with the paracausal power of Angelicas, humans was able to push back the Ghost tide and rebuild their civilization.

Now, however, it was time for the Second.

Finn Thresher was just a normal university student at first. He, like the rest of the public world, had no idea what was coming for them — but sometimes, just because you don’t know, doesn’t mean you can’t be harmed.

His family… his sight… his purpose. All lost to the paranormal.

It was time to abandon his beliefs. To throw away his morals.

After all… if these creatures weren’t human anyway, there was no point in showing them humanity.

In the first battle of this war, the Ghosts won, nearly driving the human race to extinction. In the second, the humans fought back with the power of Angelicas and managed to secure a victory.

Now, the third and final round was approaching — and this time, it’s personal.

There is a way in the world here, and the manifestation of the way is a Gu.

When people practice, they cultivate the energy of heaven and earth all over their body to drive away Gu insects and display supernatural powers.

Traveling through a year, Chen Qing finally discovered his specialness on the day he contracted the first Gu worm. He was able to see through everything about the Gu worm…

So, he started to fight steadily, step by step on the road to longevity.
